<p><P>PROBLEM TO BE SOLVED: To provide a program, an information storage medium and an image generation system, capable of expressing illumination or the like from a moving object, with reality. <P>SOLUTION: Texture coordinates for an illumination pattern texture TEX set with an illumination pattern of illumination light emitted from a vehicle object OB1 corresponding to vertex coordinates included in an object data of a course object OB2 are computed using a projection matrix for expressing spreading of the illumination light from the projection center set to the vehicle object OB1, and the illumination pattern texture TEX is texture-mapped to the course object OB2 to set an illuminated area with respect to the course object OB2. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
